Alguns aspectos operacionais e ambientais incorporados a um sistema de gerenciamento de pavimentos aeroportuários : uma contribuição metodológica à luz da análise do ciclo de vida

Abstract

A paved system of runways, taxiways, and patios is key to ensuring the full functionality of costly assets. In addition to construction costs, these pavements, in particular, require constant investments in maintenance and rehabilitation (M&R) activities throughout their lifetime, in the face of high traffic requests imposed on this structure. The airport pavement management system (APMS) arises at this time of need for rationalization of resources, not only financial ones but also natural ones. The present work develops a methodological procedure based on Life Cycle Cost Analysis (LCCA) and Life Cycle Analysis (LCA) to overcome these obstacles. The method, composed of five integrated stages, proposes the rational calculation of costs arising from the need for the runway closure for M&R services, based on machine learning techniques, and the systematic survey of environmental impacts arising from the M&R alternatives recommended by the traditional APMS. These financial and environmental components are then concomitantly considered in a Data Envelopment Analysis (DEA) modeling. During the case study, the results showed that the method could select the alternative with the best economic and environmental efficiency for each homogeneous segment of the pavement. The expense forecasts arising from the ACCV phase have also become more robust with the incorporation of costs based on runway closure time, called indirect costs.
